CanJam London 2017 show – part five

In the final part of our definitive multi-part round-up of the best personal audio products on show at CanJam London, 2017, Chris Martens and Alan Sircom feature Stereo Pravda to Westone!


Who? Micha Kucherenko, CEO, StereoPravda

What? SP5 ‘SPearphone’

When available? Now

How much? $2,000

Description:  The original SP3 and SP7 ‘SPearphone’ designs are now joined by the new SP5. As the name suggests, the five driver balanced armature design has all five drivers sharing the same axis, a universal ‘one-size-fits-all’ silicone tip (not replaceable by the user), custom made cables by Chris Sommovigo, and features a set of audiophile-grade Vischay matching resistors. Unlike most ‘in ear’ designs, StereoPravda’s ‘in the ear’ monitors live up to the ‘SPearphone’ name because they are designed to sit deeper in the ear canal than most.

What are you listening to? Jacques Loussier, Plays Bach



Who? Nigel Crump, Managing Director, Symmetry

What? Stax SRM-T8000 Energiser

When available? Now

How much? £3,895

Description:  The new Hybrid Reference Energiser from Stax has been a long time coming, and is designed to be used with the top Stax SR-009 Electrostatic Earspeakers. The new energiser features a pair of double-triode 6922 tubes on a separate board made up of vibration-proof damper and shield cover. The additional size of the energiser allows use of larger than usual toroidal transformers, and is the first Stax energiser to include a full external bypass function, for those wanting the Stax system to be used with a traditional audio system.

What are you listening to? Either Norwegian Death Metal, or Gimme Gimme Gimme by The Leather Nun (neither of these are true - my note taking had got to incoherent at this time).



Who: Nic Poulson, Trilogy Audio (Emeka from Trilogy pictured)

What? Trilogy H1 electrostatic amplifier

When available? Now

How much? £4,995-£5,295 (depending on Finish)

Description:  Trilogy Audio always wanted to make an amplifier for the Stax electrostatic, but realised most designs simply use variations on the same circuit as Stax itself. After experimenting with such designs, Nic from Trilogy went fully Tabula Rasa and started with a completely clean sheet, creating an all-valve, zero feedback, fully differential design with a direct coupled output stage. The H1 features high transconductance valves throughout and used remote control only to drive volume, balance, and input selection. The H1 is also one of the first designs not to simply go for high voltage output, thereby potentially creating micro-tears in the stator membrane. In listening tests, both AS and CM felt this is a paradigm shift in performance for the Stax SR-009. Watch this space for a review

What are you listening to? Sibelius Symphony No 1.
